CMat

A matlab file and variable interface written in moden c++ depend on matlab api

Depency： Include: Add matlab include dir(which dir contain mat.h) to your project include dirs

DLL: Add matlab lib dir(which dir contain libmat.lib/libmx.lib) to your projcec lib paths,add libmat.lib/libmx.lib to your import dll list

Code Sample: //Step1: Create A {181,23,301} Complex Double matrix * 10 into a cell named "vvv":

#include "cmat/cmatvariable.h" //or #include "cmat/cmatfile.h"

CMatVariable<mxCELL_CLASS,false> vvv("vvv",{10,1}); //create a variable named "vvv" which contain 10*1 cell for(mwSize i = 0;i < vvv.Dims()[0];++i) { CMatDataType_Cell cell = vvv.At({i,0}); cell.Retype(mxDOUBLE_CLASS,true,{181,23,301}); //retype every cell to complex double {181,23,301}

    for(mwSize j = 0;j < cell.Size();++j)
    {
        CMatDataType_Double<true> doubleData = cell[j];

        doubleData.Real() = j * 1.0;                                                      //fill some value to matrix
        doubleData.Imaginary() = j * 2.0;
    }

}

//Step2:Write the "vvv" variable to mat file "write.mat" CMatFile matFileWrite("write.mat","w"); matFile.Write(vvv); matFile.Close();

//Step3:Read the "write.mat" CMatFile matFileRead("write.mat","r"); while(CMatDataBase* vvvv = matFile1.ReadNext()) //read next variable till the end // or CMatDataBase* vvvv = matFile1.Read("vvv") to read a specific variable named "vvv" { mxClassID classID = vvvv->Type(); const std::vector &dims = vvvv->Dims();

  switch(classID)
  {
  case mxCELL_CLASS:
  {
      CMatData<mxCELL_CLASS,false> &p = dynamic_cast<CMatData<mxCELL_CLASS,false> &>(*vvvv);
      for(mwSize i = 0;i < p.Size();++i)
      {
          assert(p[i].Type() == mxDOUBLE_CLASS && p[i].IsComplex());

          CMatDataType_Double<true> doubleData = p[i].At({0,0,0});                        //read first complex double,index start from 0

          double real = doubleData.Real();
          double imag = doubleData.Imaginary();

          doubleData = p[i].At({180,22,300});                                             //read last when dims is {181,23,301} and last index is {180,22,300}
          double realLast = doubleData.Real();
          double imagLast = doubleData.Imaginary();
      }
  }break;
      //case mxDOUBLE_CLASS ...{}break;
  default:
      break;
  }
  delete vvvv;                                                                        //delete the variable pointer

}

Test(put these code on main.c):
#include #include "mat.h"

//#include "C:\Program Files (x86)\Visual Leak Detector\include\vld.h"

#include "CMat/test.h" #include "CMat/cmatdata.h" #include "CMat/cmatexception.h" int main(int argc, char *argv[]) { // QApplication a(argc, argv); try { Test *test = new Test(); delete test; } catch (CMatException_OpenMatFileFailed &e) { // std::cout << "exception:" << e.what() << std::endl; }catch(CMatException &e){ std::cout << "exception:" << e.what() << std::endl; }

// return a.exec(); }
